13B NGK Racing plug gap?

[bldn10]

I'm putting a new set of the NGK Racing plugs in my car - what is the correct gap setting? A guy at Mazda said .7 mm but that seems pretty tight.

.7mm would be .027 inches. I usek NGK in my motor & I set them tighter than .027 inches per the guy at NGK @ Wixom, MI.

What motor do you use & what plug ?

Have Fun

"13B NGK Racing"

1675-105 That's about what they were out of the box so just left them alone except I removed the washers. The ones I removed were nasty but the engine was running good w/ no misses. I hope this means it'll run even better now.
